The Screen Size Comparison tool takes the dimensions of two screen sizes and compares them against each other. Results are displayed both visually and as text data and can be used to easily discern how much larger or smaller your new screen will be.

LCD display doesn’t operate the same way as CRT displays , which fires electrons at a glass screen, a LCD display has individual pixels arranged in a rectangular grid. Each pixel has RGB(Red, Green, Blue) sub-pixel that can be turned on or off. When all of a pixel’s sub-pixels are turned off, it appears black. When all the sub-pixels are turned on 100%, it appears white. By adjusting the individual levels of red, green, and blue light, millions of color combinations are possible

The pixels of the LCD screen were made by circuitry and electrodes of the backplane. Each sub-pixel contains a TFT (Thin Film Transistor) element.  These structures are formed by depositing various materials (metals and silicon) on to the glass substrate that will become one part of the complete display “stack,” and then making them through photolithography. For more information about TFT LCDs, please refer to “

The etched pixels by photolith process are the Native Resolution. Actually, all the flat panel displays, LCD, OLED, Plasma etc.) have native resolution which are different from CRT monitors

Although we can define a LCD display with resolution, a Full HD resolution on screen size of a 15” monitor or a 27” monitor will show different. The screen “fineness” is very important for some application, like medical, or even our cell phone. If the display “fineness” is not enough, the display will look “pixelized” which is unable to show details.

PPI stands for number of pixels per inch. It is kind of pixel density. PPI describes the resolution of a digital image, not a print. PPI is used to resize images in preparation for printing

But you see other lower resolution available, that is because video cards are doing the trick. A video card can display a lower LCD screen resolution than the LCD’s built-in native resolution. The video cards can combine the pixels and turn a higher resolution into lower resolution, or just use part of the full screen. But video cards can’t do the magic to exceed the native resolution.

Aspect Ratio:  You might hear 4:3 which is full screen, 16:9 is for widescreen; 21:9 is for ultrawide computer monitors and televisions, as well as cinematic widescreen projectors. Some ultrawide monitors are trying to replace dual monitor.

In 2D screens, such as computer monitors and mobile phones, the size of the screen (also known as the viewport) is the physical size of the area where the images and videos are displayed. The size of the screen is usually described by the length of its diagonal, which is the distance between the opposite corners, usually in inches. It is also sometimes called the physical size of the image to distinguish it from the “logical size of the image”, which describes the resolution of the screen and is measured in pixels.

For the display of devices such as phones, tablets, monitors and televisions, the use of the term display resolution, as defined above, is incorrect, although common. The term display resolution is commonly used to refer to pixel size, the maximum number of pixels in each measurement (e.g., 1920 × 1080), which says nothing about the pixel density of the display in which the image is actually formed: the resolution correctly refers to pixel density, the number of pixels per unit of distance or area, and not the total number of pixels. In digital measurements, the resolution of the display will be given in pixels per inch (PPI). In analog measurement, if the screen height is 10 inches, the horizontal resolution is measured in 10 square inches.f For television standards, this is usually indicated as “horizontal resolution lines by the height of the image”; for example, analog NTSC televisions can normally display about 340 lines “by the height of the image” of horizontal resolution from above-air sources, which is equivalent to about 440 common lines of actual image information from left to right.

The method of measuring screen size along its diagonal was inherited from the method used in the first generation of CRT TVs, when circular edge photo tubes were widely used. Because they are round, the outer diameter of the bulb was used to describe its dimensions. As these round tubes were used to display rectangular images, the diagonal measurement of the visible rectangle was smaller than the diameter of the tube due to the thickness of the glass surrounding the phosphor screen (which was hidden from the viewfinder by the body and the bezel). This method continued even when the cathode ray tubes were made in the form of rounded rectangles; its advantage was that it was a unique number that determined the size and was not confusing when the aspect ratio was universal 4:3. In the USA, when almost all TV tubes had a 4:3 aspect ratio, the screen size was defined as the true diagonal of the screen with a V following it (this was a requirement in the USA market, but not in other countries). In almost all other markets, the outer diameter of the tube was specified. What was 27V in the USA may have been 28 inches elsewhere. However, in advertising in the USA the terminology V was often omitted, citing 27V as 27 inches. This was not misleading to the consumer because the law required the seller to specify the actual size of the screen. Flat panels, on the contrary, use the actual diagonal of their visible size so that the size is the actual size presented to the viewer in all markets. This means that a similar sized screen will be larger than a flat panel screen compared to a cathode ray tube screen.

When the overall aspect ratio increased from 4:3 to 16:9, the new widescreen screens in the US were marked with the letter W. The display, which is approximately 27 W high, will have an output power of 32 W. Vizio and other U.S. TV manufacturers have introduced even larger screens with a 21:9 aspect ratio to match the aspect ratio used in movie theaters. To evaluate the relative size of these new screens, it is necessary to consider the aspect ratio of the screen. In a commercial market where different aspect ratios are sold, two numbers are always needed to describe the screen size, some combination of diagonal, aspect ratio, height or width.

Dimensions are often given as a “class” because screens from different manufacturers will have small differences in size. However, the “class” must be less than 1/2″ of the actual size. The reasons for differences in size within a class are due to differences in the manufacturers’ equipment. As manufacturers change from one size to another, larger sizes should fit in the same size as the glass, although with fewer monitors cut from it. Some sizes fit well and maximize the use of glass, others fit worse and waste glass. For example, in some cases, increasing the screen size by up to 0.1 inches may cause the LCD manufacturer to move from 12 screens mounted on their glass sheets to 9, which will make them uncompetitive compared to other screen manufacturers.

To illustrate the point, here is a comparison chart we’ve developed of all modern (popular) phones, tablets and wearables. This screen size comparison chart shows the screen resolution and the pixel density of each device as well as other metrics like the CSS width.

Mimo Monitors can create a custom-size LCD monitor to almost any specification. Whether it is a minor modification to an existing design, or by utilizing our extensive experience in the industry, we can almost always build what you need.

Size –Measured in inches diagonally from corner to corner – Typical sizes are 7, 10.1, 13.3, 15.6, 18.5, 21.5. We can go bigger than this if necessary. Almost any size is possible.

Resolution - The number of pixels in the display – This will depend somewhat on the aspect ratio chosen. Higher resolution is better, but remember the pixel size on a 65” 1080p HDTV is actually 15x worse than on a 800x480 7” display. In other words, resolution doesn’t matter as much as sizes get smaller. Common resolutions are 800x480, 1024x600, 1280x800, 1366x768 1920x1080

Viewing Angle - This will depend on the technology of the LCD panel. TN vs. VA vs. IPS. More here (http://www.tnpanel.com/tn-vs-ips-va/) . In general, the better the viewing angle, the more expensive the resulting display. Typical are 150x140, 170x170 and 179x179. Or more commonly wide viewing angle or standard viewing angle.

Brightness or Luminance - It is the level of light emitted by an LCD display monitor. Luminance is reported in nits or cd/m2. They are actually the same thing.  This matters for indoor and outdoor viewing and also if you want to draw people toward the display for advertising. Typical indoor brightness is 150 nits, indoor advertising is 300, bright indoor advertising is 700 and outdoor panels are 1000+

Touch panel - Optional human interface for interactivity. Typical choices are Display Only, Resistive (4 or 5 wire), and Capacitive touch options. Our blog discusses the advantages and disadvantages of capacitive touchscreens. SAW is another touch technology that is becoming less and less common.

An LCD monitor is a flat screen using liquid crystal technology to create the display. It is used in place of CRT (cathode ray tube) monitors to display all types of verbal or graphic information.

These monitors are used wherever displays are necessary, including numerical control screens for machine tools, human-machine interfaces (HMI) or simply as industrial computer screens.

LCD monitors are among those that control the transmission or reflection of a separate light source rather than generating their own. The various technologies include twisted nematic (TN), super twisted nematic (STN), film compensated super twisted nematic (FSTN) and thin film transistor (TFT).

On 2D displays, such as computer monitors and TVs, the display size (or viewable image size or VIS) is the physical size of the area where pictures and videos are displayed. The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen"s display resolution and is measured in pixels.

The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen"s display resolution and is measured in pixels.

The method of measuring screen size by its diagonal was inherited from the method used for the first generation of CRT television, when picture tubes with circular faces were in common use. Being circular, the external diameter of the bulb was used to describe their size. Since these circular tubes were used to display rectangular images, the diagonal measurement of the visible rectangle was smaller than the diameter of the tube due to the thickness of the glass surrounding the phosphor screen (which was hidden from the viewer by the casing and bezel). This method continued even when cathode ray tubes were manufactured as rounded rectangles; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4:3. In the US, when virtually all TV tubes were 4:3, the size of the screen was given as the true screen diagonal with a V following it (this was a requirement in the US market but not elsewhere). In virtually all other markets, the size of the outer diameter of the tube was given. What was a 27V in the US could be a 28" elsewhere. However the V terminology was frequently dropped in US advertising referring to a 27V as a 27". This was not misleading for the consumer as the seller had to give the actual screen size by law. Flat panel displays by contrast use the actual diagonal of their visible display size, thus the size is the actual size presented to the viewer in all markets. This means that a similarly specified size of display will be larger as a flat panel display compared with a cathode ray tube display.

When the common aspect ratio went from 4:3 to 16:9, the new widescreens were labeled with a W in the US. A screen that is approximately the same height as a 27V would be a 32W. Vizio and other US TV manufacturers have introduced even wider screens with a 21:9 aspect ratio in order to match aspect ratios used in cinemas. In order to gauge the relative sizes of these new screens, the screen aspect must be considered. In a commercial market where multiple aspect ratios are being sold, it will always take two numbers to describe the screen size, some combination of diagonal, aspect ratio, height or width.

Set sizes are frequently given as a "class" as screens from different manufacturers will have slight differences in size. However the "class" should be within 1/2" of the actual size. The reasons for the different sizes within a class stem from differences in the manufacturers" equipment. As manufacturers move from one size to another, newer larger sizes must fit on the same size glass, though with fewer displays being cut from it. Some sizes fit well and maximize glass utilization, other sizes fit more poorly and waste glass. As an example, in some cases, increasing the screen size by even 0.1" can cause an LCD manufacturer to go from 12 screens fitting on their glass sheet to 9. This would make them uncompetitive with other screen makers.

The resolution of the human eye (with 20/20 vision) is about one minute of arc. For full HDTV resolution, this one minute of arc implies that the TV watcher should sit 4 times the height of the screen away. At this distance the individual pixels can not be resolved while simultaneously maximising the viewing area. So the ideal set size can be determined from the chart below by measuring the distance from where the watcher would sit to the screen in centimeters (or inches), dividing that by 4, and comparing with the screen heights below. At this distance, viewers with better than 20/20 vision will still be able to see the individual pixels.

The TV image is composed of many lines of pixels. Ideally, the TV watcher sits far enough away from the screen that the individual lines merge into one solid image. The watcher may sit even farther away and still see a good picture, but it will be a smaller portion of their visual field.

Common screen dimensions are listed in the table below (the most common diagonal dimensions in inches as of 2020 are bolded). If the display is not listed, then the following equations can be used. Note that D is the diagonal (in centimeters or inches), W is the width (in pixels), and H is the height (in pixels).

What is Micro OLED? Why Micro OLED is good choice for AR/VR devices. Apple"s first VR/MR headset will be launched next year. This headset will be equipped with three screens, two of them are micro OLED displays.

FFALCON innovation released the new generation of consumer XR glasses FFALCON Air 1S. uses BirdBath+MicroOLED technology to create a 130-inch high-definition screen experience for users.

The OnePlus Nord Watch features a 1.78 inch AMOLED rectangular screen with a 368x448 resolution and a 60Hz refresh rate. The watch has no built-in GPS, so it can only receive its location from a smartphone via Bluetooth 5.2.

Now LCD is the most common VR device screen on the market, and a few VR  products use OLED screens and  Mirco-OLED screens. Micro OLED is unfamiliar for VR players. Arpara 5K PC VR, the world"s first VR device,  is using the micro-OLED display.

This enhanced IPS LCD Screen is 2.9 inch 480*720, Panox Display`s convertor board on FPC make higher resolution compatible with GBA circuit board. This makes 3*3 pixels display one pixel as the original display.

BOE responded to investors about the development of AR/VR display panels, saying that BOE has provided VR/AR/MR smart applications display solutions, including high PPI, high refresh rate of Fast LCD and ultra-high resolution, ultra-high contrast of Micro OLED (silicon-based OLED) and other representative display technology.

According to India"s latest report, Samsung"s Image Display Division purchased about 48 million panels in 2021 and shipped 42 million units. In 2022, meanwhile, it plans to purchase 56 million panels and ship 48 million units in 2022. The panels it purchases will be made up of 53 million OPEN Cell LCD TVs, 1 million QD OLED panels, and 2 million WOLED TV panels.

With the explosive growth of new energy vehicles and vehicle intelligence in 2021, in-vehicle display technology has also undergone a period of rapid development. First, end-users and OEMs have begun to pursue multi-screen, high-resolution, and large-size displays. And, secondly, major panel manufacturers have actively adopted diversification strategies based on their own particular strengths and adjusted their own layouts accordingly.

AM-OLED shows the current is still in the technology leading period, folding, screen camera, narrow frame, high refresh rate, low power consumption, ultra-thin display technology popular with the market, terminal application penetration accelerated, and gradually from smartphones, smart wear small main penetration areas to the car, laptop size expansion, industry in rapid expansion period, no previous display industry facing cyclical fluctuations, the overall industry pattern initially formed.

NDSsi uses only “Grade A” LCD panels in all of its products, while many competitors use “Grade B” panels in order to save cost, and as a result compromise quality. In medical applications, it is important not to compromise the quality of the displayed image since it is often the basis for making clinical decisions. The following tables and images show the differences between “Grade A” and “Grade B” LCD panels in terms of different types of allowable defects.

There are essentially two different types of pixel defects, bright (stuck pixels) and dark (dead pixels).The table and images below show the differences between Grade A and Grade B LCD panels in terms of allowable pixel defects.

There are plenty of new and confusing terms facing TV shoppers today, but when it comes down to the screen technology itself, there are only two: Nearly every TV sold today is either LCD or OLED.

The biggest between the two is in how they work. With OLED, each pixel provides its own illumination so there"s no separate backlight. With an LCD TV, all of the pixels are illuminated by an LED backlight. That difference leads to all kinds of picture quality effects, some of which favor LCD, but most of which benefit OLED.

LCDs are made by a number of companies across Asia. All current OLED TVs are built by LG Display, though companies like Sony and Vizio buy OLED panels from LG and then use their own electronics and aesthetic design.

So which one is better? Read on for their strengths and weaknesses. In general we"ll be comparing OLED to the best (read: most expensive) LCD has to offer, mainly because there"s no such thing as a cheap OLED TV (yet).

The better LCDs have local dimming, where parts of the screen can dim independently of others. This isn"t quite as good as per-pixel control because the black areas still aren"t absolutely black, but it"s better than nothing. The best LCDs have full-array local dimming, which provides even finer control over the contrast of what"s onscreen -- but even they can suffer from "blooming," where a bright area spoils the black of an adjacent dark area.

One of the main downsides of LCD TVs is a change in picture quality if you sit away from dead center (as in, off to the sides). How much this matters to you certainly depends on your seating arrangement, but also on how much you love your loved ones.

A few LCDs use in-plane switching (IPS) panels, which have better off-axis picture quality than other kinds of LCDs, but don"t look as good as other LCDs straight on (primarily due to a lower contrast ratio).

OLED doesn"t have the off-axis issue LCDs have; its image looks basically the same, even from extreme angles. So if you have a wide seating area, OLED is the better option.

Nearly all current TVs are HDR compatible, but that"s not the entire story. Just because a TV claims HDR compatibility doesn"t mean it can accurately display HDR content. All OLED TVs have the dynamic range to take advantage of HDR, but lower-priced LCDs, especially those without local-dimming backlights, do not. So if you want to see HDR content it all its dynamic, vibrant beauty, go for OLED or an LCD with local dimming.

In our tests comparing the best new OLED and LCD TVs with HDR games and movies, OLED usually looks better. Its superior contrast and lack of blooming win the day despite LCD"s brightness advantage. In other words LCD TVs can get brighter, especially in full-screen bright scenes and HDR highlights, but none of them can control that illumination as precisely as an OLED TV.

OLED"s energy consumption is directly related to screen brightness. The brighter the screen, the more power it draws. It even varies with content. A dark movie will require less power than a hockey game or ski competition.

The energy consumption of LCD varies depending on the backlight setting. The lower the backlight, the lower the power consumption. A basic LED LCD with its backlight set low will draw less power than OLED.

LG has said their OLED TVs have a lifespan of 100,000 hours to half brightness, a figure that"s similar to LED LCDs. Generally speaking, all modern TVs are quite reliable.

Does that mean your new LCD or OLED will last for several decades like your parent"s last CRT (like the one pictured). Probably not, but then, why would you want it to? A 42-inch flat panel cost $14,000 in the late 90"s, and now a 65-inch TV with more than 16x the resolution and a million times better contrast ratio costs $1,400. Which is to say, by the time you"ll want/need to replace it, there will be something even better than what"s available now, for less money.

OLED TVs are available in sizes from 48 to 88 inches, but LCD TVs come in smaller and larger sizes than that -- with many more choices in between -- so LCD wins. At the high end of the size scale, however, the biggest "TVs" don"t use either technology.

You can get 4K resolution, 50-inch LCDs for around $400 -- or half that on sale. It"s going to be a long time before OLEDs are that price, but they have come down considerably.

LCD dominates the market because it"s cheap to manufacture and delivers good enough picture quality for just about everybody. But according to reviews at CNET and elsewhere, OLED wins for overall picture quality, largely due to the incredible contrast ratio. The price difference isn"t as severe as it used to be, and in the mid- to high-end of the market, there are lots of options.

Two measures describe the size of your display: the aspect ratio and the screen size. Historically, computer displays, like most televisions, have had an aspect ratio of 4:3. This means that the ratio of the width of the display screen to the height is 4 to 3.

For widescreen LCD monitors, the aspect ratio is 16:9 (or sometimes 16:10 or 15:9). Widescreen LCD displays are useful for viewing DVD movies in widescreen format, playing games and displaying multiple windows side by side. High definition television (HDTV) also uses a widescreen aspect ratio.

All types of displays include a projection surface, commonly referred to as the screen. Screen sizes are normally measured in inches from one corner to the corner diagonally across from it. This diagonal measuring system actually came about because the early television manufacturers wanted to make the screen size of their TVs sound more impressive.

Interestingly, the way in which the screen size is measured for CRT and LCD monitors is different. For CRT monitors, screen size is measured diagonally from outside edges of the display casing. In other words, the exterior casing is included in the measurement as seen below.

For LCD monitors, screen size is measured diagonally from the inside of the beveled edge. The measurement does not include the casing as indicated in the image below.

­Because of the differences in how CRT and LCD monitors are measured, a 17-inch LCD display is comparable to a 19-inch CRT display. For a more accurate representation of a CRT"s size, find out its viewable screen size. This is the measurement of a CRT display without its outside casing.

­ Popular screen sizes are 15, 17, 19 and 21 inches. Notebook screen sizes are smaller, typically ranging from 12 to 17 inches. As technologies improve in both desktop and notebook displays, even larger screen sizes are becoming available. For professional applications, such as medical imaging or public information displays, some LCD monitors are 40 inches or larger!

Obviously, the size of the display directly affects resolution. The same pixel resolution is sharper on a smaller monitor and fuzzier on a larger monitor because the same number of pixels is spread out over a larger number of inches. An image on a 21-inch monitor with an 800x600 resolution will not appear nearly as sharp as it would on a 15-inch display at 800x600. ­

If you’re designing a display application or deciding what type of TV to get, you’ll probably have to choose between an OLED or LCD as your display type.

LCDs utilize liquid crystals that produce an image when light is passed through the display. OLED displays generate images by applying electricity to organic materials inside the display.OLED and LCD Main Difference:

graphics and images visible. This is the reason you’re still able to see light coming through on images that are meant to be dark on an LCD monitor, display, or television.

OLEDs by comparison, deliver a drastically higher contrast by dynamically managing their individual pixels. When an image on an OLED display uses the color black, the pixel shuts off completely and renders a much higher contrast than that of LCDs.OLED vs LCD - Who is better at contrast?

Having a high brightness level is important if your display is going to be used in direct sunlight or somewhere with high ambient brightness. The display"s brightness level isn"t as important if it’s going to be used indoors or in a low light setting.OLED vs LCD - Who is better at Brightness?

Have you ever looked at a screen from an angle and noticed that the images became washed out or shadowy? The further away you get from the “front and center” view, the worse the image appears to be. This is an example of viewing angles in action – the wider the viewing angle, the better the images on screen will appear as you view them from different vantage points.

This means the display is much thinner than LCD displays and their pixels are much closer to the surface of the display, giving them an inherently wider viewing angle.

You’ll often notice images becoming distorted or losing their colors when tilting an LCD or when you view it from different angles. However, many LCDs now include technology to compensate for this – specifically In-Plane Switching (IPS).

LCDs with IPS are significantly brighter than standard LCDs and offer viewing angles that are on-par with OLEDs.OLED vs LCD - Who is better at Viewing Angles?

LCDs have been on the market much longer than OLEDs, so there is more data to support their longevity. On average LCDs have proven to perform for around 60,000 hours (2,500) days of operation.

With most LCDs you can expect about 7 years of consistent performance. Some dimming of the backlight has been observed but it is not significant to the quality of the display.

So depending on how your OLED is used, this can greatly affect its lifespan. An OLED being used to show static images for long periods of time will not have the same longevity as one displaying dynamic, constantly moving images.OLED vs LCD - Which one last longer?

There is not yet a clear winner when it comes to lifespans between LCD and OLED displays. Each have their advantages depending on their use-cases. It’s a tie!

OLED displays have higher contrast ratios (1 million : 1 static compared with 1,000 : 1 for LCD screens), deeper blacks and lower power consumption compared with LCD displays. They also have greater color accuracy. However, they are more expensive, and blue OLEDs have a shorter lifetime.

OLED displays offer a much better viewing angle. In contrast, viewing angle is limited with LCD displays. And even inside the supported viewing angle, the quality of the picture on an LCD screen is not consistent; it varies in brightness, contrast, saturation and hue by variations in posture of the viewer.

There are no geographical constraints with OLED screens. LCD screens, on the other hand, lose contrast in high temperature environments, and lose brightness and speed in low temperature environments.

Blue OLEDs degrade more rapidly than the materials that produce other colors. Because of this, the manufacturers of these displays often compensate by calibrating the colors in a way that oversaturates the them and adds a bluish tint to the screen.

With current technology, OLED displays use more energy than backlit LCDs when displaying light colors. While OLED displays have deeper blacks compared with backlit LCD displays, they have dimmer whites.

LCDs use liquid crystals that twist and untwist in response to an electric charge and are lit by a backlight. When a current runs through them, they untwist to let through a specific amount of light. They are then paired with color filters to create the display.

AMOLED (Active-Matrix Organic Light-Emitting Diode) is a different form of OLED used in some mobile phones, media players and digital cameras. It offers higher refresh rates with OLEDs and consume a lot less power, making them good for portable electronics. However, they are difficult to view in direct sunlight. Products with AMOLED screens include Galaxy Nexus, Galaxy S II, HTC Legend and PlayStation Vita.
